Methyl Folate ((6S)-5-Methyl TetraHydroFolate or 5-MTHF) is the most biologically active form of folic acid. Quatrefolic® is the 4th generation development in folate delivery. With certain inherited errors in metabolism and under a variety of physiologic stresses, the transformation of folic acid into the active form of folate either does not properly take place or is inadequate. Unlike folic acid, this form of folate can cross the blood-brain barrier. Methyl folate is needed to support cardiovascular and neurologic health and proper cell division.* Folate supplementation during pregnancy has been shown to reduce the risk of neural tube birth defects.*

Keep out of the reach of children. The elderly should frequently check B12 status when taking this folic acid as folic acid may mask pernicious anemia. If you have a medical condition, are pregnant, lactating, trying to conceive, under the age of 18, or taking medications (especially antiepileptic and chemotherapy medications), consult your health care practitioner before using this product.
